Claims

[Claims for Utility Model Registration] 1. A performance operator for inputting performance information related to a performance, a storage means for storing automatic performance data, and automatic performance data read from the storage means or input from the performance operator. a musical sound generating means that generates a musical sound based on the performance information input by the user; and a first musical sound generating means that generates a musical sound based on the performance data inputted by the performance operator.
An electronic musical instrument having two modes, a second mode in which the musical sound generating means generates musical sounds based on automatic performance data stored in the storage means, wherein an operation of the performance operator is detected. an operation detection means for detecting an operation of the performance controller when the musical tone generation means is generating a musical tone based on the automatic performance data in the second mode; an electronic musical instrument, comprising: control means for stopping musical tone generation from the musical tone generating means based on the automatic performance data and switching the mode from the second mode to the first mode when the automatic performance data is detected. 2. A performance controller for inputting performance information related to a performance, a storage device for storing automatic performance data, and a musical tone based on the automatic performance data read from the storage device or performance information input from the performance controller. a musical sound generating means that generates a musical sound; and a first musical sound generating means that generates a musical sound based on performance information inputted by the performance operator.
An electronic musical instrument having two modes, a mode and a second mode in which musical tones are generated based on automatic performance data stored in the storage means, comprising operation detection means for detecting an operation of the performance operator; In the second mode, when an operation of the performance operator is detected by the operation detection means while the musical tone generation means is generating a musical tone based on the automatic performance data, the automatic a first control means for stopping musical sound generation from the musical sound generation means based on performance data and switching from the second mode to the first mode; and a first control means for switching from the second mode to the first mode. when the first mode is switched, a timer for measuring the time during which no operation of the performance controller is detected by the operation detecting means; a second control for controlling the musical tone generating means to start generating musical tones based on the automatic performance data stored in the storage means by switching from the first mode to the second mode when An electronic musical instrument characterized by having means and. 3. The performance operator is a pitch operator for inputting pitch information or a musical tone characteristic operator for specifying musical tone characteristics of a musical tone generated from the musical tone generating means. Electronic musical instruments listed.
